POC CRDT support in Postgres
This is an experimental extension for CRDTs, `pg_crdt`. It supports Yjs/Yrs and Automerge.
The linked blog post describes how we're thinking about this extension in a Supabase context. Ideally this "Show HN" generates some discussion/interest, both here and in the github discussions .
I want to emphasise this part from the blog post: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync/support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."

A JSON-like data structure (a CRDT) that can be modified concurrently by different users, and merged again automatically.
